Hello,

This is the second take of cpu_stop. There have been only two minor
changes from the last take[L].

* work_buf initialization in stop_one_cpu_nowait() simplified.

* Comment to clarify active_balance_work synchronization added.

Peter, if you ack the series, I'll add refresh the patches w/ your ACK
and request pull into sched/core to Ingo.

This patchset contains the following four patches.

0001-cpu_stop-implement-stop_cpu-s.patch
0002-stop_machine-reimplement-using-cpu_stop.patch
0003-scheduler-replace-migration_thread-with-cpu_stop.patch
0004-scheduler-kill-paranoia-check-in-synchronize_sched_e.patch

The patches are against the current linux-2.6-tip/sched/core
(99bd5e2f245d8cd17d040c82d40becdb3efd9b69) and are available in the
following git tree.
